BACKGROUND

With the development of intelligent terminals (such as smart phones, Padand the like), the intelligent terminal has become an indispensable itemin people's lives. During using of the intelligent terminal, the useroften adjusts screen brightness of the intelligent terminal manually.For example, when the user reads a novel with the intelligent terminal,the user may decrease the screen brightness to avoid excessive damage tothe eye; when the user watches a video, the user may increase the screenbrightness to watch the video more clearly.

DETAILED DESCRIPTION

Technical solutions of the present disclosure will be described clearlyand completely with reference to the accompanying drawings; obviously,implementations described are merely part of rather than all ofimplementations of the present disclosure. Based on the implementationsof the present disclosure, other implementations obtained there fromwithout any creative work by those of ordinary skill in the art shallfall into the protection scope of the present disclosure.

According to implementations of the present disclosure, there isprovided a method for adjusting screen brightness and a user terminal,so as to adjust the screen brightness conveniently and quickly. Theimplementations of the present disclosure will be introducedrespectively in detail below.

According to an implementation of the present disclosure, there isprovided a method for adjusting screen brightness of theimplementations, in which a user terminal detects a target pressurevalue and a target touch duration of a touch operation performed in atouch area by a user, then acquires a target brightness adjustmentamount corresponding to the target touch duration according to a presetcorrespondence relationship between a touch duration and a brightnessadjustment amount when a preset condition is met, thereafter, the userterminal can adjust screen brightness based on the target brightnessadjustment amount. The method for adjusting the screen brightnessprovided in the implementations of the present disclosure will bedescribed in detail with reference to FIG. 1 to FIG. 4.

Referring to FIG. 1, FIG. 1 is a schematic flow diagram illustrating amethod for adjusting screen brightness of a first method implementationof the present disclosure. As illustrated in FIG. 1, the method foradjusting screen brightness can begin at block 102.

At block 102, a target pressure value and a target touch duration of atouch operation performed in a touch area by a user is detected.

In the implementation of the present disclosure, the target pressurevalue and the target touch duration of the touch operation performed inthe touch area by the user is detected by a user terminal. The userterminal can include but not limited to intelligent phones, PDA,laptops, desktop computers, and other user terminals with a pressuredetecting function. The operating system of the user terminal caninclude but not limited to an Android operating system, an IOS operatingsystem, a Symbian operating system, a Black Berry operating system, aWindows Phone 8 operating system and the like, and the presentdisclosure is not limited thereto.

In the implementation of the present disclosure, when the user wants toadjust the screen brightness, the user can perform the touch operationin the touch area of a touch screen. When the user terminal detects thetouch operation performed in the touch area by the user, the userterminal detects the target pressure value and the target touch durationof the touch operation performed by the user.

At block 104, when a preset condition is met, a target brightnessadjustment amount corresponding to the target touch duration is acquiredaccording to a preset correspondence relationship between a touchduration and a brightness adjustment amount.

Preset Condition 1

In this implementation, the preset condition 1 is that the targetpressure value is greater than a preset pressure threshold.

After the user terminal detects the target pressure value of the touchoperation performed in the touch area by the user, the user terminal canfurther judge whether or not the preset condition is met. In thisimplementation, the preset condition is that the target pressure valueis greater than a preset pressure threshold, in other words, the userterminal judges whether or not the target pressure value is greater thanthe preset pressure threshold.

When the user terminal judges that the preset condition is met, in otherwords, when the user terminal judges that the target pressure value isgreater than the preset pressure threshold, conduct the operation atblock 104. When the user terminal judges the preset condition is notmet, in other words, when the user terminal judges that that the targetpressure value is smaller than the preset pressure threshold, theprocess ends, or the user terminal continues to detect whether or not apressure value of the touch operation performed by the current user isgreater than the preset pressure threshold, until the finger of the userleaves the touch area (that is, the touch operation is finished).

In the implementation of the present disclosure, the user terminal maypreset the correspondence relationship between the touch duration andthe brightness adjustment amount. The brightness adjustment amount canbe a brightness increase amount or a brightness reduction amount, andthe present disclosure is not limited thereto. For example, it can beset in advance that, a brightness increase amount of 10 Candelas persquare meter corresponds to a touch duration of 2 s, a brightnessincrease amount of 15 Candelas per square meter corresponds to a touchduration of 3 s.

In the implementation of the present disclosure, when the user terminaljudges that the target pressure value is greater than the presetpressure threshold, the user terminal acquires the target brightnessadjustment amount corresponding to the target touch duration accordingto the preset correspondence relationship between the touch duration andthe brightness adjustment amount. Specifically, the user terminal canacquire the target brightness increase amount corresponding to thetarget touch duration according to a preset correspondence relationshipbetween a touch duration and a brightness increase amount, or the userterminal can acquire the target brightness reduction amountcorresponding to the target touch duration according to a presetcorrespondence relationship between a touch duration and a brightnessreduction amount.

At block 106, screen brightness is adjusted based on the targetbrightness adjustment amount.

In the implementation of the present disclosure, after the user terminalacquires the target brightness adjustment amount, the user terminal canadjust the screen brightness based on the target brightness adjustmentamount. Specifically, when the target brightness adjustment amount isthe target brightness increase amount, the user terminal can increasethe screen brightness based on the target brightness increase amount;when the target brightness adjustment amount is the target brightnessreduction amount, the user terminal can decrease the screen brightnessbased on the target brightness reduction amount.

Operations of block 102-block 106 can be repeated for multiple timesaccording to actual needs and/or application scenarios.

As can be seen from the implementations described above, the userterminal detects the target pressure value and the target touch durationof the touch operation performed in a touch area by a user; when apreset condition is met, the user terminal can acquire a targetbrightness adjustment amount corresponding to the target touch durationaccording to a preset correspondence relationship between a touchduration and a brightness adjustment amount, and adjust the screenbrightness based on the target brightness adjustment amount. As can beseen, by means of the implementations of the present disclosure, theuser only needs to perform the touch operation in the touch area toadjust the screen brightness; this can avoid the user to adjust thescreen brightness via a complex operating procedure, and can improve theconvenience of adjusting the screen brightness.

As can be seen from the method for adjusting the screen brightnessillustrated in FIG. 1, the target brightness adjustment amount can bethe target brightness increase amount or the target brightness reductionamount. The user terminal can acquire the target brightness increaseamount and increase the screen brightness based on the target brightnessincrease amount, or acquire the target brightness reduction amount anddecrease the screen brightness based on the target brightness reductionamount. Specifically, there can be a plurality of manners in which theuser terminal acquires the target brightness adjustment amount, whichwill be described in detail with reference to FIG. 2 and FIG. 3.

Referring to FIG. 2, FIG. 2 is a schematic flow diagram illustratinganother method for adjusting screen brightness of a second methodimplementation of the present disclosure. The method of FIG. 2 describesthe implementation of a target brightness adjustment amount acquiringoperation in detail based on FIG. 1. As illustrated in FIG. 2, themethod for adjusting screen brightness can begin at block 202.

At block 202, the user terminal detects a target pressure value and atarget touch duration of a touch operation performed in a touch area bya user.

Touch Area

In the implementation of the present disclosure, the touch area includesa first preset touch area and a second preset touch area, and the firstpreset touch area and the second preset touch area are two areas that donot coincide.

In some possible implementations, the first preset touch area and thesecond preset touch area can be set when the user terminal is shippedfrom a factory. For example, the first preset touch area can be theupper half of a touch screen of the user terminal, and the second presettouch area can be the lower half of the touch screen of the userterminal, and vice versa; the present disclosure is not limited thereto.

In some possible implementations, the first preset touch area and thesecond preset touch area can also be set manually by the user the userterminal.

In some possible implementations, the first preset touch area and thesecond preset touch area can also be set by the user terminal based onuser habits. For example, the first preset touch area and the secondpreset touch area can be two different areas where the touch operationhas been performed frequently in the past the use prefers to performingthe touch operation, and the present disclosure is not limited thereto.

During implementation, the process that the user terminal detects thetarget pressure value and the target touch duration of the touchoperation can refer to the description of block 102 of the firstimplementation and it will not be repeated here.

At block 204, when the target pressure value is greater than the presetpressure threshold and when the touch operation is performed in thefirst preset touch area, the user terminal acquires a target brightnessreduction amount corresponding to the target touch duration according toa preset correspondence relationship between a touch duration and abrightness adjustment amount.

In the implementation of the present disclosure, after the user terminaldetects the target pressure value of the touch operation performed inthe touch area by the user, the user terminal can further judge whetheror not a preset condition is met.

Preset Condition 2

With regard to a touch operation performed in the first preset toucharea, the exemplary preset condition, that is, the preset condition 2 isthat, the target pressure value is greater than a preset pressurethreshold.

In the implementation of the present disclosure, when the touchoperation is performed in the first preset touch area and when the userterminal judges that the target pressure value is greater than thepreset pressure threshold, proceeds to the block 204. When the userterminal judges that the target pressure value is smaller than thepreset pressure threshold, the process ends, or the user terminal maycontinue to detect whether or not a pressure value of the touchoperation performed by the current user is greater than the presetpressure threshold, until the user leaves his or her finger from thetouch area (that is, the touch operation is finished).

In the implementation of the present disclosure, when the touchoperation is a touch operation performed in the first preset touch areaand when the user terminal judges that the target pressure value isgreater than the preset pressure threshold, the user terminal acquiresthe target brightness reduction amount corresponding to the target touchduration according to a preset correspondence relationship between atouch duration and a brightness reduction amount. After the userterminal acquires the target brightness reduction amount, proceeds toblock 206.

At block 206, the user terminal decreases the screen brightness based onthe target brightness reduction amount.

In the implementation of the present disclosure, after the user terminalacquires the target brightness reduction amount, the user terminaldecreases the screen brightness based on the target brightness reductionamount.

At block 208, when the target pressure value is greater than the presetpressure threshold and the touch operation is performed in the firstpreset touch area, and when a current power value is greater than apreset power value, the user terminal acquires a target brightnessincrease amount corresponding to the target touch duration according toa preset correspondence relationship between a touch duration and abrightness adjustment amount.

Preset Condition 3

With regard to a touch operation performed in the second preset toucharea, the exemplary preset condition, that is, the preset condition 3 isthat, the target pressure value is greater than a preset pressurethreshold and the current power value of the terminal is greater thanthe preset power value.

When the touch operation is performed in the second preset touch areaand when the user terminal judges that the target pressure value isgreater than the preset pressure threshold, the user terminal canfurther detect whether or not a current power value is greater than apreset power value. When the user terminal judges that the targetpressure value is smaller than the preset pressure threshold, theprocess ends, or the user terminal may continue to detect whether or nota pressure value of the touch operation performed by the current user isgreater than the preset pressure threshold, until the user leaves his orher finger from the touch area (that is, the touch operation isfinished).

In the implementation of the present disclosure, when the user terminaljudges that the current power value is greater than the preset powervalue, proceeds to the block 208; when the user terminal judges that thecurrent power value is not greater than the preset power value, theprocess ends, or outputs inquiring information to inquire whether tocontinue to increase the screen brightness because the current power istoo low.

In the implementation of the present disclosure, when the user wants toincrease the screen brightness, the user terminal detects whether or notthe current power value is a low power. When the current power value isnot the low power, the user terminal increases the screen brightness,this helps to extend standby time and improve user experience.

In the implementation of the present disclosure, when the touchoperation is a touch operation performed in the second preset touch areaand when the user terminal judges that the current power value isgreater than the preset power value, the user terminal acquires thetarget brightness increase amount corresponding to the target touchduration according to a preset correspondence relationship between atouch duration and a brightness increase amount. After the user terminalacquires the target brightness increase amount, proceeds to block 210.

At block 210, the user terminal increases the screen brightness based onthe target brightness increase amount.

In the implementation of the present disclosure, after the user terminalacquires the target brightness increase amount, the user terminalincreases the screen brightness based on the target brightness increaseamount.

As can be seen from the implementations described above, when the userperforms the touch operation in the touch area, the screen brightnesscan be increased; when the user performs the touch operation in anothertouch area, the screen brightness can be decreased. As can be seen, bymeans of the implementation of the present disclosure, the screenbrightness can be adjusted conveniently.

In addition to the method of FIG. 2, FIG. 3 provides anotherimplementation for the target brightness adjustment amount acquiringoperation of the method for adjusting screen brightness. In FIG. 2, thetarget brightness adjustment amount acquiring operation is performedbased on different preset touch areas; in FIG. 3, the target brightnessadjustment amount acquiring operation will be performed based ondifferent preset fingerprint information.

Referring to FIG. 3, FIG. 3 is a schematic flow diagram illustratinganother method for adjusting screen brightness of a third methodimplementation of the present disclosure. As illustrated in FIG. 3, themethod for adjusting screen brightness can begin at block 302.

At block 302, the user terminal detects a target pressure value and atarget touch duration of a touch operation performed in a touch area bya user.

During implementation, the process that the user terminal detects thetarget pressure value and the target touch duration of the touchoperation can refer to the description of block 102 of the firstimplementation and it will not be repeated here.

In this implementation, after the user terminal detects the targetpressure value of the touch operation performed in the touch area by theuser, the user terminal can further judge whether or not a presetcondition is met.

Preset Condition 4

In this implementation, the preset condition 4 is that the targetpressure value is greater than a preset pressure threshold and targetfingerprint information input by the touch operation matches with presetfingerprint information.

Based on this, the user terminal may judge whether or not the targetpressure value is greater than the preset pressure threshold and whetheror not the target fingerprint information input by the touch operationmatches with the preset fingerprint information.

In some possible implementations, when the user terminal judges that thetarget pressure value is greater than the preset pressure threshold, theuser terminal further judges whether or not the target fingerprintinformation input by the touch operation matches with preset fingerprintinformation.

Alternatively, the user terminal may first judge whether the targetfingerprint information input by the touch operation matches with thepreset fingerprint information and then judge whether or not the targetpressure value is greater than the preset pressure threshold.

When the user terminal judges that the target pressure value is smallerthan the preset pressure threshold, the process ends, or the userterminal continues to detect whether or not a pressure value of thetouch operation performed by the current user is greater than the presetpressure threshold, until the user leaves his or her finger from thetouch area (that is, the touch operation is finished).

When the user terminal judges that the target fingerprint informationinput by the touch operation does not match with the preset fingerprintinformation, the process ends, or the user terminal continues to detectwhether or not fingerprint information input by the touch operationperformed by the current user matches with the preset fingerprintinformation, until the user leaves his or her finger from the touch area(that is, the touch operation is finished).

In the implementation of the present disclosure, the preset fingerprintinformation includes first preset fingerprint information and secondpreset fingerprint information, and the first preset fingerprintinformation is different from the second preset fingerprint information.

In some possible implementations, the first preset fingerprintinformation and the second preset fingerprint information can bepre-stored in a memory of the user terminal by the user in advance. Forexample, the first preset fingerprint information can be fingerprintinformation of the thumb of the user, the second preset fingerprintinformation can be fingerprint information of the index finger of theuser, and the present disclosure is not limited thereto.

When the user terminal judges that the target pressure value is greaterthan the preset pressure threshold, the user terminal further judgeswhether or not the target fingerprint information input by the touchoperation matches with the first preset fingerprint information. Whenthe target fingerprint information matches with the first presetfingerprint information, proceed to block 304. Alternatively, when thetarget fingerprint information does not match with the first presetfingerprint information, the user terminal judges whether or not thetarget fingerprint information matches with the second presetfingerprint information. When the target fingerprint information matcheswith the second preset fingerprint information, proceed to block 308;when the target fingerprint information does not match with the secondpreset fingerprint information, the process ends.

As another implementation, when the user terminal judges that the targetpressure value is greater than the preset pressure threshold, the userterminal can first judge whether or not the target fingerprintinformation matches with the second preset fingerprint information. Whenthe target fingerprint information matches with the second presetfingerprint information, proceed to block 308. Alternatively, when thetarget fingerprint information does not match with the second presetfingerprint information, the user terminal judges whether or not thetarget fingerprint information matches with the first preset fingerprintinformation. When the target fingerprint information matches with thefirst preset fingerprint information, proceed to block 304; when thetarget fingerprint information does not match with the first presetfingerprint information, the process ends.

In the implementation of the present disclosure, when the targetfingerprint information matches with the second preset fingerprintinformation and when the user terminal judges that the target pressurevalue is greater than the preset pressure threshold, the user terminalcan further detect whether or not a current power value is greater thana preset power value. When the user terminal judges that the currentpower value is greater than the preset power value, proceeds to block308.

At block 304, when the target pressure value is greater than the presetpressure threshold and the target fingerprint information matches withthe first preset fingerprint information, the user terminal acquires atarget brightness reduction amount corresponding to the target touchduration according to a preset correspondence relationship between atouch duration and a brightness adjustment amount.

In the implementation of the present disclosure, when the user terminaljudges that the target fingerprint information matches with the firstpreset fingerprint information, the user terminal acquires the targetbrightness reduction amount corresponding to the target touch durationaccording to the preset correspondence relationship between the touchduration and the brightness reduction amount. After the user terminalacquires the target brightness reduction amount, proceeds to block 306.

At block 306, the user terminal decreases the screen brightness based onthe target brightness reduction amount.

In the implementation of the present disclosure, after the user terminalacquires the target brightness reduction amount, the user terminal candecrease the screen brightness based on the target brightness reductionamount.

At block 308, when the target pressure value is greater than the presetpressure threshold and the target fingerprint information matches withthe second preset fingerprint information, the user terminal acquires atarget brightness increase amount corresponding to the target touchduration according to a preset correspondence relationship between atouch duration and a brightness adjustment amount.

In the implementation of the present disclosure, when the user terminaljudges that the target fingerprint information matches with the secondpreset fingerprint information, the user terminal acquires the targetbrightness increase amount corresponding to the target touch durationaccording to a preset correspondence relationship between a touchduration and a brightness increase amount. After the user terminalacquires the target brightness increase amount, proceeds to block 310.

At block 310, the user terminal increases the screen brightness based onthe target brightness increase amount.

In the implementation of the present disclosure, after the user terminalacquires the target brightness increase amount, the user terminal canincrease the screen brightness based on the target brightness increaseamount.

As can be seen from the implementations described above, when a userperforms a touch operation using a finger, screen brightness can beincreased; when the user performs the touch operation using anotherfinger, the screen brightness can be decreased. As can be seen, by meansof the implementation of the present disclosure, the screen brightnesscan be adjusted conveniently.

FIG. 1 to FIG. 3 illustrates the implementation of screen brightnessadjusting operation. After the screen brightness is increased, the userterminal can further output screen brightness excessive alarms when theuser terminal detects that a current screen brightness value is greaterthan a preset brightness threshold so as to protect the eyes of theuser, which will be described in detail with reference to FIG. 4.

Referring to FIG. 4, FIG. 4 is a schematic flow diagram illustratinganother method for adjusting screen brightness of a fourth methodimplementation of the present disclosure. As illustrated in FIG. 4, themethod for adjusting screen brightness can begin at block 402.

At block 402, the user terminal detects a target pressure value and atarget touch duration of a touch operation performed in a touch area bya user.

During implementation, the process that the user terminal detects thetarget pressure value and the target touch duration of the touchoperation can refer to the description of block 102 of the firstimplementation and it will not be repeated here.

At block 404, when the target pressure value is greater than the presetpressure threshold, the user terminal acquires a target brightnessadjustment amount corresponding to the target touch duration accordingto a preset correspondence relationship between a touch duration and abrightness adjustment amount.

In the implementation of the present disclosure, after the user terminaldetects the target pressure value of the touch operation performed inthe touch area by the user, the user terminal will judge whether or nota preset condition is met. In this implementation, the preset conditioncan be that the target pressure value is greater than a preset pressurethreshold. The user terminal can judge whether or not the targetpressure value is greater than the preset pressure threshold. When theuser terminal judges that the target pressure value is greater than thepreset pressure threshold, proceeds to the block 404. When the userterminal judges that the target pressure value is smaller than thepreset pressure threshold, the process ends, or the user terminalcontinues to detect whether or not a pressure value of the touchoperation performed by the current user is greater than the presetpressure threshold, until the user leaves his or her finger from thetouch area (that is the touch operation is finished).

At block 406, the user terminal adjusts screen brightness based on thetarget brightness adjustment amount.

In the implementation of the present disclosure, after the user terminaladjusts the screen brightness based on the target brightness adjustmentamount, the user terminal will detect whether or not a current screenbrightness value is greater than a preset brightness threshold. When theuser terminal detects that the current screen brightness value isgreater than the preset brightness threshold, proceeds to block 408;when the user terminal detects that the current screen brightness valueis smaller than the preset brightness threshold, the process ends.

At block 408, when the current screen brightness value is greater thanthe preset brightness threshold, the user terminal outputs screenbrightness excessive alarms.

In the implementation of the present disclosure, the user terminal canoutput screen brightness excessive alarms in the form of voice or text,the present disclosure is not limited thereto.

In practice, excessive screen brightness will cause damage to the eyesof the user. In the implementation of the present disclosure, when theuser adjusts the screen brightness to excessive brightness, alarms areoutput to the user, so that the user can take measures to protect theeyes, thus improving user experience.

In the implementation of the present disclosure, the user terminal 500may preset the correspondence relationship between the touch durationand the brightness adjustment amount. The brightness adjustment amountcan be a brightness increase amount or a brightness reduction amount,and the present disclosure is not limited thereto. For example, it canbe set in advance that, a brightness increase amount of 10 Candelas persquare meter corresponds to a touch duration of 2 s, a brightnessincrease amount of 15 Candelas per square meter corresponds to a touchduration of 3 s.

In the implementation of the present disclosure, when the targetpressure value is greater than the preset pressure threshold, theacquiring unit 504 acquires the target brightness adjustment amountcorresponding to the target touch duration according to the presetcorrespondence relationship between the touch duration and thebrightness adjustment amount.

In some possible implementations, the touch area includes a first presettouch area and a second preset touch area, and the first preset toucharea and the second preset touch area are two areas that do notcoincide.

When the touch operation is performed in the first preset touch area,the target brightness adjustment amount is a target brightness reductionamount, and the adjusting unit 506 is further configured to decrease thescreen brightness based on the target brightness reduction amount.
